Step-by-step explanation:
Simply put, it says that the numbers can be added in any order, and you will still get the same answer. For example, if you are adding one and two together, thecommutative property<span> of addition says that you will get the same answer whether you are adding 1 + 2 or 2 + 1. This also works for more than two numbers.</span>
2.4080 meters.
Remember that the definition of work is force over distance. And that the gravitational potential energy that the turtle has will exactly match the work performed in lifting it. So have the following variables
Mass = 860.24 kg
Work = 20320.7 J = 20320.7 kg*m^2/s^2
Gravitational acceleration = 9.81 m/s^2
And we wish to get an answer in meters. So we need to multiply and divide the three numbers we have with all their related units and derive an answer with the unit of m. We can cancel out most of the units by dividing the work by the gravitational acceleration, so
20320.7 kg*m^2/s^2 / 9.81 m/s^2 = <span>
<span>2071.427 kg*m
Now we can cancel out the kg unit by dividing by the mass of the turtle. So

2071.427 kg*m / 860.24 kg = </span><span>
<span>2.407964 m
Rounding to 5 significant figures gives 2.4080 meters.

Answer:
14
Step-by-step explanation:
To find the perimeter, you need to add the lengths of each side.
In order to find the length of each side, imagine each side of the given triangle is the hypotenuse of an imaginary triage and use the Pythagorean Theorem (a² + b² = c²).
For the top side, I see an imaginary triangle with one side of 3 and the other side of 1. This means the length of the top of the given triange is √10:
3² + 1² = c²
9 + 1 = c²
10 = c²
√10 = c
For the left side, my imaginary triangle has one side of 5 and the other is 1. The length of this side is √26:
5² + 1² = c²
25 + 1 = c²
26 = c²
√26 = c
For the right side, I see a triange with two sides of 4 and the hypotenuse is √32.
This means the triangle in our question has side of √10, √26, and √32
If I add all of these up on a calculator, I get 13.918 which rounds up to 14 because the question wants the nearest whole unit.
